What is a PTFE solenoid valve? PTFE solenoid valve structure and working principle

What is a PTFE solenoid valve? PTFE solenoid valve (also known as corrosion-resistant plastic king solenoid valve) is made of polytetrafluoroethylene. It has zero-pressure start, stable performance, good sealing, and long life. PTFE solenoid valve is used in strong acids, strong alkali, strong oxidants and solvents. Strongly corrosive fluid media and ultra-pure fluids. For example, automatic control of pipelines such as concentrated acid, strong acid, various electroplating solutions, aromatic solvents, aliphatic solvents, and high-clean fluids. Solenoid valves are widely used in mechanical equipment, petrochemical industry, chemical reagent factories, chemical analysis instruments, sewage treatment equipment, scientific research instruments and other corrosive media automatic fluid control products. Features of PTFE solenoid valve 1. The valve body is made of PTFE (king of plastics), the seal is made of fluororubber or PTFE, and other parts are completely isolated from the liquid medium. 2. It adopts piston action type and isolation seal, with zero leakage. 3. The working pressure is -0.1MPa (10Torr) to 1.6MPa, especially suitable for low-pressure systems. 4. Reliable action and no noise. 5. Power saving, power consumption is 50% of similar products. Chemical resistance and stability of PTFE solenoid valve 1. Resistance to strong acid (98% concentrated acid, solvent), strong alkali, strong oxidant and other highly corrosive fluid media;2. Excellent atmospheric aging resistance, anti-oxidation, anti-surface scale, Anti-fading and anti-brittle properties;3. No pollution, odorless, high purity and chemical inertness, will not have any impact on fluid media, and is suitable for ultra-pure fluids, water treatment, etc. 4. Wide temperature range: it can be used for a long time in the range of –50°C to +180°C. PTFE solenoid valve structure technology 1. Piston structure, opening and closing quickly, not easy to block, unique soft sealing process sealing technology, no dripping;2. The seals are imported high-tech products, with strong corrosion resistance and can withstand various Strong acid, strong alkali and strong oxidant can be used for a long time without damage;3. The fluid medium is isolated from other metal parts. PTFE solenoid valve structure and working principle This valve is a step-action direct pilot solenoid valve. It can be divided into normally closed type and normally open type according to the different switching status when the power is cut off. Normally closed type: When the solenoid valve coil is energized, the armature first drives the auxiliary valve to open under the action of electromagnetic force, and the main valve opens under the action of the formed medium pressure difference and electromagnetic force. When the solenoid valve coil is powered off, the armature component is reset, and the main and auxiliary valves are tightly closed using the medium pressure. Normally open type: When the solenoid valve coil is energized, the armature moves downward under the action of magnetic force, pushing the auxiliary valve plug downward until it is pressed against the auxiliary valve seat and the auxiliary valve closes. Since the pressure difference between the upper and lower parts of the main valve cup tends to be equal, The main valve cup is tightly sealed by magnetic force and self-weight pressure, and the valve is closed. When the solenoid valve coil is powered off and the magnetic force is zero, the armature and the auxiliary valve plug rise due to the action of the spring, the auxiliary valve opens, the medium in the main valve cup flows away through the auxiliary valve, the pressure drops, and the main valve cup is affected by the upper and lower pressure difference. When it rises upward, the main valve opens and the valve is opened. The above is what is a PTFE solenoid valve? An introduction to the working principle of the PTFE solenoid valve structure.
